A white, \u003cstrong\u003ereflective and light-tight skin\u003c\/strong\u003e keeps light off your nutrient solution – which helps stop algae taking hold – and reflects heat rather than soaking it up, so the solution stays nearer the 18–21°C AutoPot recommend.

It assembles in minutes without tools, comes with all the fittings including the bottom tap, and packs back down into its slim box when the grow is finished.
